10 pages, 9 figures.-- Published in: "Polarimetry in Astronomy", edited by Silvano Fineschi.-- Contributed to the conference with same title, Waikoloa, HI, USA, Aug 25, 2002., Final full-text version available Open Access at: http://www.iaa.es/~jti/publications/SPIE.pdf, The description of the Imaging Magnetograph eXperiment (IMaX) is presented in this contribution. This is a magnetograph which will fly by the end of 2006 on a stratospheric balloon, together with other instruments (to be described elsewhere). Especial emphasis is put on the scientific requirements to obtain diffraction-limited visible magnetograms, on the optical design and several constraining characteristics, such as the wavelength tuning or the crosstalk between the Stokes parameters.

6 pags., 10 figs., The authors present the results of the ellipsometric characterization of thin layers of bismuth and aluminum oxide deposited over the waist of a tapered optical fiber by pulsed laser deposition. The characteristics of the deposits are studied by spectroscopic ellipsometry. From the effective thicknesses determined by the ellipsometric characterization, it is shown by simulations that surface plasmon resonances (SPRs) can occur in the fiber device, and it is demonstrated experimentally. These results show the feasibility of employing bismuth as a plasmonic material in SPR fiber sensors based on doubly-deposited uniform-waist tapered optical fibers, which show excellent performance and versatility., This work has been partially funded by Spanish Project (No. RTI2018-096498-B-I00) (MCIU/AEI/FEDER, UE) and by Santander-UCM Research Project (Ref.
